1. for the boys, 3 soccer is 5 basketball (in a group of 8 students).
2. for the girls, 7 soccer is 1 basketball (in a group of 8 students)
3. the question mentions 90 boys like soccer, which means we increased the number of boys surveyed 30x, since 3 times 30 is 90. now, we need to increase the girl numbers by 30 as well, giving us 210 girls who like soccer for every 30 who like basketball.

Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Part 1: The option (A) is correct. The prediction of the event is 32 spins.
Part 2: Option (B) is correct. The probability of the event is 139 passwords.
Part 3: The P(yellow or blue) is 2/6.
Part 4: Option (B) is correct.
Part 5: Both options (A) and (C) are correct.
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Part 1:
The option (A) is correct. The prediction of the event is 32 spins.
For the given situation,
Number of segments the spinner has n = {1,2,3,4}
The event is the number of times the spinner will be spun before the number 2 appears 8 times
In one spin there are four possibilities. So to get the number 2 appears 8 times it becomes \(4\) × \(8\) \(= 32\)
Thus, the option (A) is correct. The prediction of the event is 32 spins.
Part 2:
Option (B) is correct. The probability of the event is 139 passwords.
For the given situation,
The password is generated by using numbers 0 through 9 and uppercase letters.
Numbers 0 to 9, total = 10 numbers
Uppercase letters = 26 letters
So, Total characters = \(10+26=36\)
The event is the prediction for the number of passwords in which the first character is a number.
The probability of the event is given by \(\frac{10}{36}\)
⇒\(0.27\)
Total passwords generated = 500
The prediction for the number of passwords in which the first character is a number = \(0.27\) × \(500\)
⇒\(138.8\) ≈ \(139\)
Thus the probability of the event is 139 passwords. Option (B) is correct.
Part 3:
The P(yellow or blue) is 2/6.
For the given situation,
The deck has total number cards = 30 cards
Blue cards = 6 cards
Red cards = 6 cards
Yellow cards = 6 cards
Brown cards = 6 cards
The probability of drawing a yellow card or a blue card is
\(P(e)=P(yellow or blue)\)
⇒\(P(e)= P(yellow) + P(blue)\)
⇒\(P(e)= \frac{6}{30} + \frac{6}{30}\)
⇒\(P(e)=\frac{12}{30}\)
⇒\(P(e)= \frac{2}{6}\)
Thus the P(yellow or blue) is 2/6.
Part 4:
From definition, Option (B) is correct.
For the given statements by definition,
UNIFORM probability is the probability model of each outcome occurring is the same.
A NON- UNIFORM probability is the probability model of each outcome occurring is not the same.
Thus from definition, Option (B) is correct.
Part 5:
Both options (A) and (C) are correct.
For the given situation,
Total number of markers = 16
Red markers = 5
Blue markers = 6
Yellow markers = 5
The number of markers are different for different colors.
So the given situation models the non-uniform probability, and the
individual outcomes are not the same.
Thus both options (A) and (C) are correct.

area = 4*8/2=16
Then, find the area of the rectangle.
a=wl (area = width * length)

Polygon JKLM is drawn with vertices J(−4, −3), K(−4, −6), L(−1, −6), M(−1, −3). Determine the image coordinates of L′ if the pre-image is reflected across y = −3.
L′(−3, 6)
L′(−1, 6)
L′(−1, 0)
L′(1, 0)
Answers
To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).
A rectangular prism with dimensions 5 inches by 13 inches by 10 inches was cut to leave a piece as shown in the image. What is the volume of this piece? What is the volume of the other piece?
HELP
Answers
The volume of the original rectangular prism is given by:
V1 = length x width x height
= 5 inches x 13 inches x 10 inches
= 650 cubic inches
To find the volume of the remaining piece, you need to determine its dimensions. If you have an image or a description of the piece, you can use that information to calculate its volume. Once you have the volume of the remaining piece, you can subtract it from the volume of the original rectangular prism to get the volume of the piece that was cut out.
To find the volume of the other piece, you can subtract the volume of the piece that was cut out from the volume of the original rectangular prism:
V2 = V1 - V_cut_out
where V_cut_out is the volume of the piece that was cut out.
